Code Mercenaries

This command resets the LW04 to the same status

as a power up does, it can not be combined with

any write commands.

5.1.11 Register 15: Sequence Table Writing

Sequence mode allows the LED-Warrior04 to

autonomously perform dynamic lighting scenarios.

This can be used to generate a power on fading,

continous changing light situations, flashing, color

changing, or any other lighting applications where

a dynamic lighting without a external controller

driving it is required.

Sequence mode is controlled by a table containing

time and PWM values. The table is specified in

5.2.

Before writing to register 15 it has to be enabled by

setting bit 5 of register 12 to "1". The write bit is

automatically reset when the table has been written

completely or an error condition occured.

Each write transaction to register 15 can contain 1

to 9 data bytes. Write transactions automatically go

to ascending table positions until an error condition

is detected, or the table is complete.

Reading from register 15 returns a two byte status

for the sequence table. If the table has been written

successfully the first byte contains the number of

bytes written and the second holds a checksum

generated by xoring all table bytes.

In case of an error the first byte is set to zero and

the second byte contains the error code:

$00 -

$01 - Write bit has been reset before a complete

table header was transmitted

$02 - Write bit has been reset before a complete

table (number of data sets according to table

header) was transmitted

$04 - More data sets than specified in the table

header have been written

$08 - Write access to other registers terminated the

table writing

$10 - Write attempt to register 15 without write

enable bit being set.

$20 - Length data in table header specify too many

data sets (>81).

5.1.12 Broadcast Commands

LED-Warrior04 implements three I2C broadcast

commands. Broadcast comamnds are write only

and are send to address 0.

$04 followed by one data byte sets the I2C address

of the LED-Wariror04 to the data byte as the new

I2C address, values 1…127 are valid.

$0A triggers the activation of new brightness

values for all LED-Warrior04 in sync mode (set in

$0B followed by one data byte sets the dimming

source on all connected LED-Warrior04

simulatneously. This is useful to synchronously

start sequence mode on several LED-Warrior04.

The data byte has only two active bits:

Bit 0 - unused, write 0

Bit 1 - unused, write 0

Bit 2 - unused, write 0

Bit 3 - unused, write 0

Bit 4 - Dimming source 0

Bit 5 - Dimming source 1

Bit 6 - unused, write 0

Bit 7 - unused, write 0

Dimming source selects which bus is active or if an

autonomous sequence controls the channels:

0b00 - I2C

0b01 - DMX512

0b10 - DALI

0b11 - Sequence Mode

5.2 Sequence Mode Control

If sequence mode is enabled as the active dimming

source and a valid sequence table has been loaded

LED-Warrior04 will work autonomously executing

the sequence table.

The sequence table is made up of the table header

and up to 81 data sets.

The table header contains the following 10 bytes:

Byte 0 - Sync 0/1

Byte 1 - Sync 2/3

Byte 2 - Repeat 0

Byte 3 - Repeat 1

Byte 4 - Repeat 2

Byte 5 - Repeat 3

Byte 6 - Length 0

Byte 7 - Length 1

Byte 8 - Length 2

Byte 9 - Length 3

Sync contains the flags for each channel to

synchronize with other channels. Sync 0/1 contains

the sync bits for channel 0 in the lower half byte

and for channel 1 in the upper half byte. Sync 2/3

contains the sync bits for channels 2 and 3.

If a sync bit is set the channel waits for the

corresponding channel to come to the end of its

sequence instance before it continues with the next

iteration of its own sequence.

I.e. if Sync0/1 is $04 then channel 0 will wait for

channel 2 to reach the end of its sequence iteration

before it starts its own next iteration. If channel 2

had already reached its sequence iteration end then

channel 0 will continue immediately. Setting

Sync0/1 to $12 will cause channels 0 and 1 to wait
